INFLUENCE OF LOW-FREQUENCY ELECTROMAGNETIC FIELD ON THE VEGETATIVE GROWTH OF GRAPE cv. USLU
low-frequency electromagnetic fi eld vegetative growth
2010/12/3
Low-frequency electromagnetic fi eld (ELF) at 50 Hz, 0.15 mT was applied to canes of ‘Uslu’ grape for 5, 10, 15 and 20 minutes. The canes were prepared by cutting them into 50-60 mm one-bud scions. Th...
